Area is length times width.
You are given the area and the width, so to find the length, divide the area by the width:
Length = Area / width
Length = 57 / 15 = 3.8 m.
Because the width is given as a set number, 15m, this would be a direct variation.
Using the exponential function, it is found that the oxygen level at 10 miles is of 59.87 ppm.
<h3>What is the exponential function for the oxygen levels?</h3>
The oxygen levels in ppm for an altitude of x miles at the Mount Everest is given by the following exponential function:
In this problem, the altitude is of x = 10 miles, hence the oxygen level in ppm is of:
